Patented July 15, 1930 WILLIAM S. PRITCHARID, OF DETROIT, MICHIGAN,ASSIGNOR TO MOTOR PRODUCTS OORPORA'IION, OF DETROIT, MICHIGAN, ACORPORATION OF NEW YORK PULLMAN WINDOW Application filed. February 27,1928.

The invention relates to window construction and more particularly to animproved means for detachably securing the glass panel within the sash.

The invention has as one of its primary objects to provide a window ofthe above type distinguished by its simplicity of construction andfacility with which the same may be attached to the standard carconstruction and with which the usual glass panel may be installed, allof which not only enhances its value both mechanically and commercially,but provides a design of a strong and durable nature.

The invention finds particular utility in Pullman car constructionwherein it is necessary to frequently replace the glass panel due tobreakage or other defects. In the particular type of window now more orless universally employed, serious disadvantages have been commonlyexperienced in assembling the glass panel in the sash owing to thevarious complicated means utilized for this purpose. The presentinvention as briefly outlined above ofiers the possibility ofeliminating complicated and inefficient securing means for the glass andrenders possible the production of a commercially satisfactory windowconstruction in which the glass panel may be readily installed.

It is a further object of the present invention to provide aconstruction wherein the glass panel securing means not only func tionsto detachably hold the glass panel in position within the sash, but alsocooperates with a portion of the Pullman car to accu rately guide thewindow during the opening or closing of the same.

While in particularizing upon the advantages and features of the presentinvention, particular stress has been placed upon the association of thewindow with Pullman cal construction. It will be immediately apparent tothose skilled in this art that the invention may be used in whole or inpart in connection with various other forms of constructions wherewindows are desired.

Many of the advantages and much of the commercial value andacceptability of the invention is attributed to the construction SerialNo. 257,485.

of the sash, these advantages being obtained particularly because of thesimplicity, of the construction and the minimum number of parts employedfor securing the glass panel in place. The invention therefore dependsfor some of its advantages upon the specific details of constructionillustrated and about to be described.

Other objects and novel features of construction will be made moreapparent as this description proceeds especially when considered inconnection with the accompanying drawings wherein Figure 1 is a sideelevation of a window constructed in accordance with my invention,

Figure 2 is a sectional view taken on the plane indicated by the line 22of Figure 1,

Figure 3 is a sectional view on the line 83 of Figure 1.

Figure 4 is a sectional view on the line 4.4 of Figure 1.

Referring now to the drawings, it will be noted that there isillustrated generally a portion of a standard Pullman car constructionin which 10 is a pillar having secured upon the outer surface thereof,a. substantially U-shaped reinforcing member 11 terminating in thelateral flanges 12 and 13. Spaced inwardly from the front face of thepillar and secured to the side surface 14 thereof is a guide member 15,which as shown cooperates with the lateral flange 12 to form a run-way16 for the vertically movable glass panel 17 constituting the outerwindow of the Pullman car. The inner window 18 being slidably mounted inthe runway 19 formed by the inner surface of the guide 15 and the usuallatch rack 20.

Referring now to the particular construction of the sash members 21 and22 for the inner and outer windows 17 and 18 respectively, it will benoted that these members are preferably constructed of sheet metal andare provided with stiles 23 and upper and lower rails 2% and 25respectively, which as shown are substantially channel-shaped in crosssection and are secured together in any suitable manner such for exampleby means of the corner brackets 26. The outer walls 27 and the innerwalls 28 of the rails and stiles of the outer and inner sash members 21and 22 respectively are bent inwardly intermediate the ends thereof asindicated at 28 forming shoulders 29, which as shown terminate in openreturn bent portions 30, while the inner walls 31 and the outer walls 31of the stiles and rails of the outer and inner sash members 21 and 22respectively are formed with an L-shaped rabbet 32 for receiving theusual packing for the glass panel and terminate in open return bentportions 33. The outer ends 34 of the portions 33 projectinto the openreturn bent portions and the outer ends 35 of the return bent portions30 project into the open return bent portions 33 so that an interlockingengagement is accomplished between the opposite walls of the rails andstiles. Thus from the fore going, it will be immediately apparent thatthe rails'and stiles are formed of a single piece of metal bent to forma closed channel and have the opposite ends thereof held in interlockingengagement. The bottom 36 of the lower rail of the sash 21 is bentupwardly as indicated at 37 forming a longitudinally extending pocket 38for receiving a suitable weather excluding strip 39 having theprojections 40 arranged to engage the stool 41. This lower rail is alsoprovided with the usual sliding ventilator construction indicatedgenerally at 42. To prevent rattling of the windows, I provide theanti-rattler members 43, which as shown are of the usual constructionand are secured to the stiles adjacent the outer edges thereof, and arearranged to yicldably engage the outer and inner walls of the guidemember 15.

In order to provide a neat construction and at the same time effectivelysecure the glass panel within the sash, I provide the glazing strips 44and 45 secured respectively to the outer walls of the rails and stilesof the sash 21. The rails and stiles of the inner sash 22 are alsoprovided with glazing strips 46 and 47 respectively, which as shown aresecured to the inner walls of the stiles and rails. The strips 44 and 46are provided at one end with the packing engaging portions 48 and at theopposite ends with the lateral projections 49 arranged to seat upon theshoulder 29 and engage the return bent portions 33. The strips 45 and 47which are secured to the stiles of bot-h the inner and outer sashmembers 21 and 22 differ from the strips 44 and 46 in that they areprovided with return bent portions 50 and 51 intermediate the endsthereof. These return bent portions engage the shoulders 29 of thestiles and abut the return bent portions 33 thereof and terminate inlateral flanges 52 and 53 respectively, which as shown are positionedadjacent to and spaced laterally from the walls 27 and 27 of the stiles.The flange 52 extends across the outer surface of the flange 12 and isprovided with a longitudinally extending bead 53 having a bearingengagement with the outer surface of the flange 12 to accurately guidethe window during openingor closing of the same. IVith such anarrangement, the amount of frictional resistance between the relativelyremovable parts is reduced to a minimum owing to the fact that the innerarcuate surface of the bead is-the only part of the flange 52 thatactually engages the flange 12. It will further be noted that the flange52 is of substantially the same length as the window and is reinforcedat the lower end thereof by means of the clip 54 secured to the bottomrail of the sash 21 and having a portion 55 embracing the flange 52. Theflange 53 of the inner glazing strip also serves as a guide for theinner window and is provided with a longitudinally extending head 56arranged to engage the outer surface 57 of the latch rack 20. The flange53 in addition to cooperating with the latch rack to accurately guidethe window also functions to fill the space between the stiles of thesash 22 and the latch rack.

For securing the glazing strips to the stiles and rails, I provideheaded elements 57 extending through threaded apertures 58 formed in theglazing strips and anchored in the return bent portions 30 and 33 of thestiles and rails. As shown the headed elements are provided with anenlarged threaded portion 59 and a reduced shank portion 60, the latterhaving a length substantially greater than the length of the threadedportion. \Vith this arrangement, when it is de sired to remove theglazing strips, it is not necessary to remove the headed elements fromthe strips but merely to unscrew the same from the stiles anl rails.Thus the danger of the elements working loose and becoming lost iseliminated and the attaching and detaching of theglazing strips isgreatly facilitated If, however, it is desired to remove the ele' mentsfrom the strips, the former are merely backed out through the threadedapertures 58. It will also be noted that the elements 57 upon threadedlyengaging the return bent portions 30 and 33 engage four thicknesses ofmetal, thereby providing ample threads for these elements so that thelatter may be securely tightened to rigidly secure strips upon thestiles and rails.

As described the window is of simple construction and of a minimumnumber of parts, it being noted that the glazing strips 46 and 47 inaddition to securing the glass panel in position cooperate with portionsof the car to accurately guide the windows during the sliding movementof the same.
